This bachelor thesis is focused on the internet of things and GPS navigation applications. The first part of the thesis consists of theoretical basics to familiarize the reader with the internet of things, its development, areas of use and security. Currently, built in navigation devices and navigation applications in smartphones are used separately, the internet of things is going to change that. In the second part todays GPS navigation applications are analyzed and compared based on the selected criteria and it is verified if the navigation applications for smartphones can replace the built in solution of BMW X5. The applications are compared based on their functions. The aim of this thesis is to analyze each of the selected applications and compare them based on the selected criteria and choose the best replacement for the built in solution until there are combined solutions available with synchronization between the built in navigation system and a navigation application.

This thesis has one secondary and two primary goals. The first primary objective is to analyse the most widely used mobile web browsers and most popular mobile navigation. Applications are evaluated on the basis of defined criteria, which is assigned a weight using the Saaty method of paired comparison. Information obtained from this analysis are used to accomplish the second primary goal. The second primary goal is to analyse the most widely used mobile platforms and find out which platform has available the best navigation and browsers. The secondary objective of this work is to acquaint the reader with the most popular mobile plat-forms. Reading this work will help reader in choosing a mobile navigation, mobile web brows-er or a mobile operating system for his mobile devices.

This Bachelor's thesis focuses on particular mobile platforms and chosen contemporary directions in mobile applications' sphere. The first part includes theoretical base. It means introduction, characteristic and development of widespread platforms in order to explanation of gradually increasing functions and opportunities offered by the modern applications to a reader. There are two mobile applications' directions chosen on the grounds of varied functions in this part of the thesis. These two directions are analysed according to fixed standards and evaluated afterwards in the next part of the thesis. The chosen directions refer to a smartbanking and mobile phone navigations. The main aim of the Bachelor's thesis is to analyse every chosen direction according to fixed standards and compare mobile applications contained in these chosen directions. The last thing is on the basis of the previous analysis and comparison to come to an conclusion which applications dominate and which are leg behind by contrast.
